Abstract

PURPOSE: To uniformize the operation of incineration plants, by changing a preset O2 mixing target value related to the temperature of a combustion chamber measured in a flue gas to make control more sensitive. CONSTITUTION: The temperature of a combustion chamber as control value 6 as well as O2 temperature content indicated as measured value 7 are determined in a flue gas 2 to be discharged from incineration plants 1. Two values 6 and 7 are fed to a controller 8. The measured O2 moist content is used as a reference value for the presumed optimum operation method. If only a change in the temperature of the combustion chamber occurs, this change must be above the preset allowable difference limit and hence, the O2 moist target value is shifted by a controller 8. The corrected O2 moist target value is fed as control value 9 to a controller 3 which inturn, works a supplying device to vary a fuel feed. The measured steam mass flow rate mD fed to a controller 5 as control value 10 to monitor the supply of combustion air.

うな制御概念の中で５上位の制御量として用いることに
よって迅速に反応する制御が行われる。PRIOR ART In well-known methods of this type, thermal measurements, such as combustion chamber temperature and steam mass flow, and material measurements, such as moisture content, are determined on the one hand. keeping the combustion efficiency constant, i.e. keeping the steam mass flow constant, and on the other hand minimizing the emissions of resident substances,
602 - moisture content, which can be linked to the reduction of harmful substances contained in the flue gas, such as carbon oxides, dust particles, hydrocarbons and nitrogen oxides, in such a control concept. By using this as a control variable for the 5th higher order, control that responds quickly can be performed.

発明が解決しようとする課題 この方法における欠点は、ｏＺ−湿・含有量が、０２−
乾・含有量を、従って真の空気過剰率を厳密に表示して
はいないという事実である。Problems to be Solved by the Invention The disadvantage of this method is that the oZ-moisture content is 02-
The fact is that the dry content and therefore the true air excess rate are not strictly indicated.

それにしても、燃焼ガスの０２−乾・含有量の測定は、
鈍ぶ過ぎ、実際の操業状態の場合には不確実過ぎる。In any case, the measurement of the 02-dry content of combustion gas is
Too dull and too uncertain for actual operating conditions.

また蒸気質量流量を一定に保持する場合には、煙道ガス

、ごみ焼却設備の場合には燃料の組成が大きく変化する
ために避けることができない。このため、効率を希望値
に設定すると、排出値が悪化することがある。02-Moisture/content as the upper price target value is kept constant,
Also, if the steam mass flow rate is kept constant, variations in the moisture content of the flue gas will result in changes in the combustion chamber temperature. However, this variation in the moisture content of the flue gas is unavoidable in waste incineration plants due to the large changes in the composition of the fuel. Therefore, if the efficiency is set to a desired value, the emission value may deteriorate.

このため、上位目標値としての０２−湿・含有量が一定
に保たれている場合に、燃焼室温度を一定に保持すると
、煙道ガスの湿分含有量が変動することによって、蒸気
質量流量が変化するようになり、この結果、全設備の熱
利用が悪化することがある。For this reason, if the combustion chamber temperature is held constant when the upper target value 02-moisture content is kept constant, the steam mass flow rate is This can result in poor heat utilization for the entire facility.

環境に対する排出値を低減させることが重要なために、
物質的量、すなわち０２−湿・含有量が、熱酌量、すな
わち蒸気質量流量および燃焼室温度よりも上位に置かれ
る。Because it is important to reduce emissions to the environment,
The material quantities, ie 02-moisture content, are placed above the thermal extenuating quantities, ie steam mass flow rate and combustion chamber temperature.

本発明の目的は、初めに述べた既知の方法の２つの修正
を基にして、排出値も、燃焼効率をも最適化することで
ある。The aim of the invention is to optimize both the emission values and the combustion efficiency on the basis of two modifications of the known method mentioned at the outset.

課題を解決するための手段 この目的は、２とおりの方法によって解決することがで
きる。Means for Solving the Problem This objective can be solved in two ways.

煙道ガス中で測定した０２−湿・含有量を、燃料供給を
制御するための上位目標値・制御量として用い、また測
定した蒸気質量流量を、一次空気供給を制御するための
下位目標値・制御量として用いるという方法に基づく場
合には、この課題は、予め設定した０２−湿・目標値を
、煙道ガス中で測定した燃焼室温度に関連付けて変化さ
せることによって解決できる。The 02-moisture content measured in the flue gas is used as the upper target value/control variable for controlling the fuel supply, and the measured steam mass flow rate is used as the lower target value for controlling the primary air supply. Based on the method of use as a control variable, this problem can be solved by varying the predetermined 02-humidity target value in relation to the combustion chamber temperature measured in the flue gas.

最初の修正方法を実施する場合、２つの温度点が限界値
として設定されるが、上の温度値を上に越えることによ
ってｏＺ−湿・目標値は高くなり、一方下の温度限界値
を下に越えることによって、ｏＺ−湿・目標値は低くな
る。最初の場合には、“見せかけの″空気過剰率も高く
なり、一方２番目の場合には、“′見せかけの“。When carrying out the first modification method, two temperature points are set as limit values, but by exceeding the upper temperature value the oZ-humidity target value becomes higher, while by lowering the lower temperature limit value. By exceeding , the oZ-humidity target value becomes low. In the first case, the “spurious” air excess rate is also high, while in the second case the “spurious”.

空気過剰率は低くなる。しかし選ばれた限界値の中に燃
焼室温度がある限り、０２−湿・目標値はいかなる影響
も受けない。The excess air ratio will be lower. However, as long as the combustion chamber temperature is within the selected limit values, the 02-humidity target value is not affected in any way.

同じような方法で、２番目の修正方法も実施できるが、
この場合は２つの温度限界値の代りに２つの蒸気質量流
量が選ばれ、これを上に越え、ないし下に越えることに
よって、ｏＺ−湿・目標値は高く、ないしは低くなる。The second modification method can also be implemented in a similar manner, but
In this case, instead of two temperature limit values, two steam mass flows are selected, by exceeding or below which the oZ-moisture target value becomes higher or lower.

環境に対する排出値が特に重要なために、本発明による
方法の場合にも、物質的値、すなわちｏＺ−湿・目標値
が優先的に取り扱われる。Due to the particular importance of emission values for the environment, the material values, ie oZ-moisture target values, are also treated preferentially in the method according to the invention.

本方法の優れた具体性に従い、０２−湿・目標値を変化
させる場合、測定した温度ないし蒸気質量流量値の変化
速度を考慮することによって、さらに良好な制御精度が
達成される。Due to the great specificity of the method, even better control precision is achieved by taking into account the rate of change of the measured temperature or steam mass flow value when changing the 02-humidity setpoint value.

この様式の場合は、温度変化ないし蒸気質量流量変化の
時間に関する微分も考慮するので、限界値に達してしま
う前に、０２−湿・目標値の変化を実施することができ
、これによって制御が敏感になるので、燃焼設備の操業
はさらに均一になる。In this case, the differentiation of temperature changes or steam mass flow rate changes with respect to time is also taken into account, so changes in the 02-humidity/target value can be implemented before the limit value is reached, which allows the control to be carried out. The increased sensitivity results in more uniform operation of the combustion equipment.

置に働きかける。The steam mass flow line flowing out of the boiler is measured at the same time by 4, and this control variable 10 is sent to a further control device 5.

この結果、温度値の許容差上限を越えることによって、
０２−湿・目標値は高くなり、一方、許容差下限を下廻

The 02-humidity/target value becomes high, while the 0□-humidity/target value becomes low by falling below the lower limit of the tolerance. Furthermore, this correction 02-moisture target value is sent as a control variable 9 to the control device 3, which acts on the supply device to change the fuel supply or acts on the grate stirring device to change the grate speed. . In contrast to the known method shown in FIG. 1, the control device 3 also deals not with the measured 0□-humidity value, but with the 02-humidity target value modified in relation to the combustion chamber temperature.

This measurement value is also measured in the flue gas 2 discharged from a combustion installation 1 consisting of a combustion section and a boiler. This measurement value 6
is sent to the control device 8. Control device 8 at the same time as receiving
is the steam mass flow rate measured by 4 by the controlled variable 10
send as The control device 8 changes the control variable 6 only when the steam mass flow rate deviates from a preset reference value bandwidth. In other words, when the steam mass flow rate exceeds the lower limit value, the 02-humidity/target value becomes high, and when the steam mass flow rate falls below the lower limit value, the 02-humidity/target value becomes low, and the corrected control amount 11 as control device 3
sent to. The control device 3 changes the combustion feed or changes the combustion grate speed depending on the corresponding deviation of the o2-humidity setpoint value. The combustion chamber temperature measured in the flue gas is sent as a subordinate control variable 12 to a control device, which monitors the amount of combustion air fed in.
